The importance of adequate UVA protection is apparent with improved understanding of UVA-induced skin damage. This has led to the development of new sunscreen ingredients. A number of regulatory bodies or experts from the industry and academia have proposed methods to assess the efficacy of sunscreens against UVA radiation. In addition different proposals have been made regarding the labeling for UVA protection. The purpose of this paper is to describe several in vitro methods for measuring UVA protection of sunscreen products and to consider their validity. The different proposals in terms of UVA labeling are also presented and discussed. This review illustrates the need for standardization of the measurement conditions and harmonization to convey to consumers the most appropriate information on UVA protection.
随着对 UVA 诱导皮肤损伤的理解不断深入,充分的 UVA 防护显得尤为重要。这促使了新型防晒成分的开发。一些监管机构或来自工业界和学术界的专家提出了评估防晒霜抵御 UVA 辐射效果的方法。此外,关于 UVA 防护的标签也有不同的建议。本文旨在描述几种测量防晒产品 UVA 防护的体外方法,并考虑其有效性。还提出并讨论了不同的 UVA 标签建议。本综述表明,需要对测量条件进行标准化和协调,以便向消费者传达有关 UVA 防护的最合适信息。
